Hear every on-screen rumble or explosion with the Cyclonix Passive, as it recreates the lowest possible audible frequencies for the ultimate cinema experience at home.

For those who prefer a subwoofer with no built-in amplifier, the Cyclonix Passive provides a passive subwoofer experience, using a high excursion bass driver mounted in a high quality MDF enclosure. The proprietary Krix ‘X’ brace system is used to eliminate panel resonances. 

The giant 455mm bass driver features a 100mm voice coil, powerful vented magnetic circuit and double spider assembly. The optimum cooling system provides fast heat exchange and reduced thermal power compression.

The dual front-vented enclosure is tuned to achieve maximum output, resulting in an incredibly efficient subwoofer for high drive level applications, while the unit’s proprietary Krix rubber feet provide improved acoustic isolation on hard and soft floor surfaces.

A separate power amplifier is also required for this subwoofer and can be connected to the LFE output of any AV processor or receiver.

For the ultimate cinema experience at home, play it through Krix.
